What Our Patients Say

“After being shot twice in my dominant arm as a police officer, I was left with permanent radial nerve damage and a long road of uncertainty. I went through four surgeries with other providers, always hoping for a breakthrough, but instead I kept hitting the same wall – weakness, pain, and the fear that I would never truly get my hand back. Switching to Dr. K changed everything. He didn’t just treat an injury; he understood what the injury had taken from me. His skill, compassion, and belief in my potential gave me a second chance at a life I thought I had lost. For the first time since the shooting, I’ve been able to rebuild strength, regain function, and genuinely thrive again. Dr. K didn’t just perform surgery — he helped rebuild my confidence, my direction, and the quality of life I thought I’d never get back.”

“Dr. Kadzielski is a caring, compassionate, and exceptionally skilled orthopedic surgeon. I came to him with complex arthritis-related elbow issues that significantly limited my ability to use my arm—especially difficult as we were eagerly awaiting the arrival of our first grandson. Thanks to Dr. K, my elbow was restored, and I was able to hold my grandson confidently in my arms. I am forever grateful for the remarkable care and renewed quality of life he has given me.”

Mary Ann Blackmur

“I am forever grateful for the extraordinary care I received from Dr. John Kadzielski. After suffering a catastrophic arm injury, as a result of gunfire, I was staring at the very real possibility of losing most of the function in my left arm. Through his exceptional surgical skill, steady guidance, and unwavering commitment, Dr. Kadzielski performed numerous complex surgeries that ultimately saved my arm. Because of his expertise and dedication, I was given the chance not only to recover, but to regain meaningful use of my arm—something that once felt impossible. Dr. K restored the function that allows me to do the things I love and, most importantly, to take care of my children. His work changed the course of my life, and I will always be thankful for the remarkable care he provided.”

“On December 5th, 2022, I began to feel some pain in my right forearm. By December 9th, with a 4 day fever and my arm being swelled up twice the size it normally is from my hand to my underarm, and in incredible pain, I went to a local hospital ER. With God’s blessing, Dr. Kadzielski was on duty. He diagnosed me almost immediately with Necrotizing Fasciitis. I spent ten days in the hospital with three surgeries to clean the arm of the deadly infection, and a fourth surgery in which Dr. Kadzielski performed a skin graph from both legs to close up the large wound. Dr. Kadzielski not only saved my arm, and 95% of the muscles in it, he saved my life! I’ve been working at my company, ‘Khoury Brothers Stump Grinding, LLC’ since my recovery in May of 2023. I’m also blessed to be able to coach my son in baseball and football. I can’t thank Dr. Kadzielski enough. He was very realistic with the possible outcomes, and very caring throughout the entire ordeal. Dr. Kadzielski is the best hand and upper extremity expert in the world!”

“One of the best doctors I’ve ever met. Incredibly knowledgeable with great people skills. Takes a great history, listens, and comes up with a thoughtful treatment program. Also not quick to do surgery. Once of the nicest things about this office is that you can tell that they people who work there really like each other, from the X-ray technician to the front desk staff. Really great experience.”
